T 0 all whom it may concern:

Be it known that we, IVILLIAM H. INsLnY and ALVIN C. RirsM ssnN, citizens of the United States, residing at Indianapolis,in the county of Marion and Stateof Indiana, have invented a new and useful. Hoisting Apparatus, of which the following is a specification.

In that type of building-material hoisting apparatus which comprises a mast, as distinguished from a tower, the earlier form was of such character that the mast could not be guye'd at intermediate points; the bridge pan was carried by the hoisting bucket and in its operation required agreater amount of power than was required in the main hoisting of the bucket, so that, merely for this bridge pan operation, a larger power unit was required; and the hoisting bucket could not be readily detached from the mast so thatthe apparatus was practically limited in'its use to't'he handling of fresh concrete mixture. 1

The object of our present invention is to improve various details of construction, so that the mast may be Zguyed at intern'xediate points without interfering with the vertical movement of the hoisting member; so that the bridge pan may be operated without the expenditure of'much power,.thereby permitting the use of smaller power unit and an operation of the bridge pan at slow speed; and so that interchangeable load-carrying members, such, for instance, as an automatically discharging bucket for handling concrete, a platform suitable 'forthe reception of loaded wheel barrows, etc, maybe readily associated with and disassociated from the mast and hoisting cable.

The accompanying drawings illustrate our invention. .Fig. 1 is a side elevation of our improved plant, showing the hoisting bucket in raised position; Fig. 2 a fragmentary side elevation of the hoisting bucket, bridge pan and adjacentparts; Fig. 3 a horizontal section on line of Fig. 2; Fig. 4a section von'line i-e of'Fig. 3; Fig. 5 a side elevationsimilar to Fig. 2 showing an elevator platform suitable for thejreception of wheel, barrows-and otherloads; :llig. 6 a section on line 66 ofFig. 2; and Fig. 7 a section-on line 77 of Fig.5.

Inthe drawings, 10indicates a mast of suitable height, supported at its bottom by a step 11, and at its top by guy Wires 12. At suitable intermediate points,'depending upon the total height of the mast, we a rrange short channel sections 13 alongside the rear face of the mast andto these sections 13 may be attached suitable guy wires 14.

Along each front corner of the mast, we arrangean angle iron 15 which extends from top to bottom of the mast, thus providing laterally-extending flanges or tracks for the ed to receive ,afsupport or pivot pin 26 of the hopper-end 27 of the "first chute section.

Pivoted at 28, 28, on the frame 23 are two parallel links 29, 29, the outer ends of which are pivoted to the bridgepan 30. Pivoted to the outer endof each upper ,link 29 is a link 31 which is pivoted at its upperend to alever frame .32 pivoted at 3301c frame The hoisting bucket for mush concrete comprises a main body 40, having a hopper bottom 41, provided witha downwardlyinclined discharge .spout42, which has an arc-shaped end 43 preferably just within the adjacent dimensions. of the main body ofthe bucket.

Pivoted at 4e on spout. 42 is a controlling gate 45 formed tov cooperate with the arcshaped end 43 of spout 42 Pivoted at ,46 upon each si-deof the gate 45 is a link 47, the upper end of which is pivoted to lever 48, fulorumed at .4:9 on bucket .40 and. having its upper end extended above the bucket, in such way that-at the upper endof its movement, it will come into contactwiththe gibbet arm 20 and be depressed thereby as thebucket moves upwardly- The bucket A0 is providedwith .a. hoisting bail 50, to which hoistingcablefil is attached, said cable being carried up over suitable pulleys 52 at the upper end of the mast and from thence to a suitable power plant 53.

, ciently distant from the adjacent portion of .a consequence, the bucket,

clearance. As in its upward movement, will clear the hopper 24: and the bridge pan 30. As it nears the upper end of its stroke, bucket 40 will come into conthe bucket to permit adequate tact with lever 32 and will raise and project the bridge pan 30 to position shown in full lines in Figs. 1 and 2, the amount of force re uired being merely suflicient to raise the weight of the parts and, as a. consequence, the bucket 10 may be brought slowly'to its final position.

At about the time the bridge pan 30 is projected far enough to thoroughly receive the discharge from spout L2, lever l8 comes into contact with the gibbet arm 20 and gate 45 is lifted, so that the contents of the bucket will bedischarged across pan 30 into hopper 24 and from thence to hopper 27 and the connected chute section. At each rear upper corner of the bucket 40, we provide a rearwardly-projecting flange flush with the side of the bucket. Adjacent each flange 60and parallel therewith, is a rearwardly projecting flange 61, provided with a rearwardly open notch 62.

The plate 63 adapted to be'bolted by bolt 64: to flange 60 and the adjacent portion of the body 10, carries a bearing sleeve 65 at right angles to flange 60, and this bearing sleeve at its outer end carries a vertical plate 66 which may be bolted by bolts 67 to flange .61, the shaft 68 entering and lying within slot 62. i

' 'Shaft 68 of a wheel 69 isjournaled in the bearing sleeve 65 and contacts with the rear face of flange 15.

The angle irons 61 are bolted to the main body of hopper 40 and at their .lower ends are extended down some distance below the main body 40 of the bucket. 1

'At the lower end of each angle iron 61 we secure a channel 70, in which is journaled shaft 71 of a roller 72, said roller contacting with the forward face of the adjacent flange 15.

Adjacent each roller 72 we attach to angle iron 61 an angle 73, one arm of which is arranged parallel to the axis of the wheel 72 and overlaps the adjacent arm of angle 15, the arrangement being such as to prevent accidental displacement of the bucket structure, relative to the mast. However, by removing angles 73 and by removing bolts 6 1, so that. the roller structure 63'69 may be bodily removed, the hoisting bucket may be readily separated from the mast and a different load-carrying member substituted, for instance, a hoisting'platform 80,

provided with rollers 69 and 72, like those already described and cooperating with the angles 15 in the same manner, may be provided for the handling of wheel barrows or dry loads of any kind, said platform 80 being provided with a hoisting bail 81 or any other suitable member, to which the hoisting cable may be attached, the connection being preferably such that the load will be fairly well balanced on the cable.

It will be readily understood that the substitute load-carrying members may take many different forms, depending upon the character of theloads to be carried, without departing from our invention.
